4.4.4 Encoder Output
The drive internally processes the signal from the encoder, and outputs them in the
form of pulses. The pulses are output using the line drive method through the pins
allocated by default to the I/O connector (1~6). The pulses can be output using the
open collector method depending on the setting of the encoder output mode
[0x3007].
Output using the open collector method uses the DO06 (PHASE A), DO07 (PHASE
B), DO08 (PHASE B) ports allocated by default to digital output signal, masking the
corresponding output function.
You can set the number of encoder pulses output per 1 rotation with the encoder
output pulse [0x3006] value.

The encoder signal output frequency of the drive is up to 200 [Kpps] when using the
open collector method, and up to 2.0 [Mpps] when using the line drive method.
The motor rotational speed is limited depending on the set value of number of
encoder output pulses per rotation: therefore, an appropriate value should be set.
Example) when outputting 50000[ppr] using the line drive method, up to 2400[rpm]
can be achieved.

Encoder Output Signal of the Line Drive Method
Outputs divided encoder signals
(Phase A, B, Z) using the line drive
method. The output division can be
set at [0x3006].
